Title: Spray attachment
Inventor: HARRIS DAVID ALAN
IPC: A01M7/00
Filed: 1961-06-23
Abstract: 959,478. Crop sprayers. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 12, 1962 [June 23, 1961], No. 22820/61. Heading B2F. A vehicle-mounted sprayer attachment comprises a first arm pivotally mounted on the vehicle, said first arm being adapted to move freely in a plane at right angles to the longitudinal axis of the vehicle and being pivotally connected to a second arm carrying discharge means, said second arm being capable of movement in a plane parallel to that containing the first arm, means biasing the second arm in an extended position and means enabling the discharge means to move at a constant height from the ground. The first arm 1 is pivoted at 11 to a support 12 and at the end of the arm 10 is a flange 25, Fig. 2, and a section of soft rubber in a polythene supply pipe 23 is normally squeezed between this flange and a member 17. The member 17 is a safety guard attached to the second arm 13 extending from the end of the boom and carrying a roller wheel 15. As the support 12, e.g. part of a tractor, advances along a row of trees at a distance equal to the length of the spray boom the roller wheel 15 comes into contact with a tree and the arm 13 pivots backwards, resulting in the release of the tubing and admission of spray liquid to tube 24 and thence to nozles 22. When the tree has been passed the piston 21 of a cylinder 19 is advanced by hydraulic pressure, using the spray fluid as the pressure medium, and swings the arm 13 back again and so cuts off the spray supply. Thus, only the ground about the base of the tree is sprayed. In a modification, the arm 13 is not biased hydraulically but by torsion springs around its pivot and when it is moved back its motion is translated through linkage into the lateral motion of a rod 35, Fig. 6, which moves a Y-shaped lever 37 and causes it to depress a wedge 44 and open a valve 38, releasing the spray fluid. For spraying ground at the foot of bushes the second arm and d nozzles are comprised by a curved tube 50, Fig. 8.

Abstract: 391,661. Treating sewage. HARTLEY, C. J., Cae Brest, The Avenue, Harpfields, Stoke-on-Trent. Aug. 18, 1932, No. 23137. [Class 111.] Relates to apparatus for aerating sewage comprising channels one above the other and having sections so connected that liquid passes alternately along a section of the upper channel and a section of the lower channel, as described in Specification 323,156, [Class 111, Sewage &c.]. According to the present invention, adjacent ends of adjacent channels are connected by horizontal bends. Fig. 1 shows an arrangement comprising three compartments A<1>, B<1>, C<1>, in each of which a two-storey sectional channel is arranged about a midfeather A<2>, to form a double circuit. The sections of the two-storey channel have connections A at each if which liquid flowing in the upper channel of one section is directed into the lower channel of the next section and viceversa. Liquid from the inlet B passes twice round the compartment A<1> and then through a pipe c to the compartment Bl and so on. Fig. 2 shows a modified arrangement in which the channels are arranged so that liquid from an inlet H takes a serpentine path through alternate upper and lower sections of all the channels and is then returned through a channel J to make a second circuit flowing in each section in the upper channel, where it previously passed through the lower one and in the lower channel where it previously passed through the upper. After the second circuit it is discharged through an outlet K. Modified apparatus is described in which after the second circuit part of the liquid passes to setting tanks and part is returned to join the entering liquid. An arrangement is described in which apparatus as shown in Fig. 1 is used for reconditioning sludge and used in combination with apparatus as shown in Fig. 2, wherein sewage is subjected to treatment with the activated sludge. The channels may be provided with baffles as described in Specification 203,534, [Class 111, Sewage &c.], and air may be blown in to promote aeration.

Patent GB-423371-A (GB)
Title: Improvements relating to aircraft
IPC: B64C27/54
Filed: 1933-08-22
Abstract: 423,371. Aircraft with rotary wing systems. FLETTNER, A., 7, Neue Bayreutherstrasse, Berlin. Aug. 22, 1933, No. 23355. [Class 4] An aircraft having rotating wings hinged to a freely movable wing hub has its wings hinged to members rotatably mounted in the hub and furnished with levers connected by links with a movable controller. Normally the links prevent rotation of the wings about their axes as the hub tilts Provision may also be made for automatically changing the incidence of the wings from an autorotative position to one suitable for a positive drive and vice versa dependent upon the speed of rotation of the system or upon variation of torque upon the hub. Fig. 2 shows a wing 2 hinged to a member 15 journalled in a hub 14 mounted upon gimbals on a shaft 3. The member 15 has an arm 17 extending to a point in a plane passing through the shaft 3 at right angles to a plane containing the shaft 3 and member 15. The end of the lever is connected by a link 19, Fig. 3, to a controller 22 mounted on gimbals on the shaft 3 and tiltable in any direction by a ring 23 having a handle 24. Instead of the whole wing being pivoted to the member 15 only the wing tip 2<a> or a rear flap may be connected to a member 15<a> as also shown in Fig. 2. Alternatively, the main blades 2 may be hinged to the hub 14 and smaller blades placed between them connected to the control member 22. A counter propeller on a transverse axis may be provided at the rear of the machine to counteract driving torque and forward thrust may be given by a tractor propeller or by arranging the shaft 3 at a forward inclination. To ensure a change of incidence of the wings with variation of speed, each wing may be mounted to move axially along a shaft 26, Fig. 5, under control of a spring 27, screwed parts 28, 29 co-operating with screwed sleeves on the wing frame to produce a change of incidence as the wing moves axially. By using screwed parts of different pitch a helical twist can be given to the blade as the mean pitch increases. Fig. 6 shows a modification in which the wing is carried by a sleeve 32 which slides over a nut 35, axial movement being controlled by a light spring arranged between arms 37, 38. A wing tip 2a is mounted on a sleeve 34 rotating in the sleeve 32 and engaging a screw 33 on the control rod 31. The wing tip consequently changes its incidence as the wing moves axially while remaining under the control of the rod 31 and lever 17. Provision for giving a helical twist to the wing and its tip may be made. Fig. 9 shows the hub 14 connected to an extension 39 of the shaft 3 by a quick threaded screw so that failure of the driving torque causes relatively axial movement of the parts 3, 39 and the incidence of the wings is reduced through their connection to the controller 22 which is mounted as shown on the member 3. A freewheel is disposed between the engine and the shaft 3.
